What does the simplicity design principle state about the use of language?

• A. A design should communicate clearly in the user's native language
• B. Text should be concise and jargon-free
• C. Language should be formal and technical
• D. Use of multiple languages in the UI

Answer: (A)

Simplicity in language means the design communicates clearly in the user’s native language. This makes messages, prompts, and labels instantly understandable, reducing confusion and cognitive load. When users see content in a language they naturally know, they can act on it quickly and accurately, which is at the heart of a simple, effective interface. While keeping text concise and avoiding jargon helps readability, the key idea here is matching the user’s linguistic background to ensure clarity. Using a formal or technical tone can create distance or confusion for everyday tasks, and introducing multiple languages in the UI adds unnecessary complexity.
